Application filed April 11, 1912.

Serial No. 689,953.

To all whom it may concern:

Be it known that I, EDWARD E. TREVIL- LION, a citizen of the UnitedStates, residing at Newellton, in the parish of Tensas and State ofLouisiana, have invented certain new and useful Improvements inNut-Locks, of which the following is a specification.

The present invention relates to nut locks, and while it moreparticularly relates to novel means for permanently locking the nutsonto fish plates of rails and to prevent the nuts from becoming loosenedon account of vibration caused by trains passing over the rail joints,the invention broadly contemplates the provision of means for lookingbolts and nuts against turning wherever it is desirable to look a nutupon its bolt.

The object of the invention is to provide a device of the abovecharacter, by which the washer may be utilized between the nut and themember to be secured, to hold the nut against rotation and to providesuch a construction of washer that the same may be held against rotationwhen applied to the fish plate or other member, and by the engagement ofthe washer with the nut to maintain the latter in a fixed position.

A further object is to so-construct the parts with these ends in viewthat the invention may be applied to common forms of nuts and boltswithout necessitating any changes whatever in their construction.

For a full understanding of the present invention, reference is to behad to the following description and to the accompanying drawings, inWhich- Figure l is a perspective view showing the improved form of nutlock applied to a rail and fish plates. Fig. 2 is a top plan View of thenut lock. Fig. 3 is a sectional view of the same taken onthe line 33 ofFig. 2. Fig. 4 is a sectional view on the line 4-4 of Fig. 2. Fig. 5 isa detail perspective view of a portion of the improved form of washer,particularly showing the upstanding arms provided with eyes, hereinafterreferred to. Fig. 6 is a side elevation of the device partly in section.Fig. 7 is a plan view of the washer before the arms which engage the nuthave been bent into operative position.

Throughout the following detail description and on the several figuresof the drawings, similar parts are referred to by like referencecharacters.

Referring particularly to the drawings, I indicates sections of abuttingrails and 2 the fish plates joining the same.

3 represents a bolt passing through the fish plates and web of the rail,said bolt having the ordinary threaded portions 4.

5 represents a nut of the ordinary construction but shown in thedrawings as having a square form, and between the nut 5 and fish plate 2is placed the improved form of washer 6, the particular construction ofwhich forms the principal novel features of my invention.

In its essential features, the washer comprises a plurality of dependinglips which are adapted to bite under lips formed on the fish plate, andwhich are adapted to be bent downwardly somewhat at the edges of thebolt hole. By the blow of a hammer,

each lip on the fish plate may be forced downwardly upon the lip of thewasher which it engages, and thus effectively maintain the washeragainst rotation or movement in any direction.

It further comprises a series of radial upstanding arms, each providedwith an eye, and adapted to engage the sides of the nut, a wire beingpassed through the eyes entirely around the nut, and thus maintain thenut in a fixed position with reference to the washer.

The improved form of washer may be stamped from a single piece of metal,and no further workmanship is required other than slight manipulation tothe portions which form the eyes before referred to.

I will now proceed to particularly describe the construction of thewasher. It is provided in its central portion with an aperture 7,through which the bolt passes, and at preferably four diametricallyopposite positions on the body of the washer, I cut the body at 8, thecuts extending from the outer periphery of the blank to a point adjacentto the aperture 7, thus forming a series of radial arms 9, each of whichis slitted at 10, and on the insertion of a sharp instrument beneath theslitted portions, an eye will be formed on each arm of the shape shownparticularly in Figs. 5 and 6.

The outer por- I tions 11 between the arms 9 of the blank are then cutaway down to the edge 12, forming a washer such as particularly shown inFig. 7 At preferably two diametrically opposite points of the peripheraledge 12, I cut the body of the washer so as to form a pair ofdepending'lips 13, and the same operation is performed at preferably twopoints on an edge of the aperture 7, forming depending.

lips 14. I may further cut out portions of the washer at 15, and formthe two depending projections or lips 16, which latter feature, however,is particularly useful when the washer is to be mounted on a woodenmember instead of the ordinary fish plate.

While my invention may be applied to almost any metallic or woodenplates which it is desired to hold together by means of bolts and nuts,in the drawings, I have shown it as applied to an ordinary fish plateand as a cooperating feature with those just described with respect tothe washer 6, I provide the fish plate at preferably two diametricallyopposite points with small recesses 17 forming slightly upwardlyinclined lips 18, the same being in a position corresponding to theposition of the lips 13 formed on the washer.

When the parts are to be assembled, the washer 6 is passed over thethreaded portion of the bolt 3 and the two lips 13 are brought to theposition of the two recesses 17 formed in the fish plate, whereupon thelips are sprung into the recesses and under the corresponding lips 18 ofthe fish plate. This arrangement of the parts is best illustrated inFig. t and after the parts are in the position described, a blow with ahammer is exerted 011 the portions of the washer surrounding the lips13, and onthe lips 17 of the fish plate, this operation tending to forcethe lips 13 into the recesses as far as they can go, and to force thelips 18 tightly down upon the lips 13. By virtue of this arrangement, aremarkably strong attachment of the washer to the fish plate is securedand rotation of the washer in any direction is prevented. At the sametime, the lips 14: will be bent downwardly so as to tightly engage theedges of the bolt 3, this operation assisting in maintaining the washeragainst rotation.

It will be understood that by the method of forming the arms 9 on thewasher hereinbefore described, a construction is afforded whereby nutsof the ordinary constructions and ofvarying sizes may be used inconnection with the present invention, since each arm 9 may be bent at apoint anywhere between the edge 11 and the innermost ends of the slits.After the washer has been fixed in position on the fish plate in themanner described, the nut 5 is then screwed upon the bolt 3, after whicheach of the arms 9' is bent upwardly into the position shown moreparticularly in Figs. 3, 5 and 6, so as to closely grasp the sides ofthe nut. 'A wire 19 is then passed through each of the eyes formed onthe arms 9 so as to completely surround the nut, and its ends may betied in any manner desired. A suflicient length may be used so as topass twice around the nut and each time pass through the eyes or, as isshown in Fig. 6, the wire will pass through the eyes only during one ofits windings about the nut, and on its second winding it may pass aboutthe outer ends of the arms.

When a washer of the construction described and particularly shown inFig. 7, is to be applied to a metallic member such as a fish plate,additional lips 20 may, if desired, be formed in the fish plate, toengage the lips or projections 16 formed in the washer and beforereferred to, the engagement being effected in the same manner as hasbeen described in regard to the lips 13 and 18; or the washer may beapplied and held in place by the engagement only of the lips 13 and 18,thus dispensing with the use of the lips 20. When, however, theinvention is to be applied to wooden members, to hold the same in place,the lips 16 may be made to bite down into the wood, and thus effectivelymaintain the washer against rotation with respect to the wooden memberwith which it is placed in contact.

By the construction above described, it will be seen that I haveprovided a simple and inexpensive means of preventing the rotation of anut upon its bolt and also of the washer with respect either to the boltor the member against which it is placed. The washer being effectivelysecured against rotation either upon a fish plate or a wooden member,the arms will be held firmly against the sides of the nut by means ofthe wire which encompasses the nut and passes through the eyes formed inthe arms and it will be obvious that by this means, any movement of thenut will be prevented. The washer being held against rotative movementwith respect to the substructure, the wire will thus positively preventmovement of the nut with respect to the washer.

Having thus described the invention, what is claimed as new is:

1. In a nut lock, the combination of a washer adapted to surround a boltand be disposed between a substructure and a nut, said washer having anoutstanding arm stamped from the material of the washer and projectingoutwardly a distance less than the thickness of the nut, the material ofthe arm being stamped into a laterally extending eye projecting awayfrom the nut, and a cable adapted to surround the nut and extend throughthe eye.
